CENTRIFI-IGAL MACHINE.

" Application filedApril 13,

To all 107mm it may concern:

Be it known that I, Eowann l). l\"I.-\cr'.i.\ 'i'osu, of the borough ofBrooklyn, in the of New York, county of Kings, and State of New York,have invented certain new and useful Improvements in CentrifugalMachines, of which the following is a specification.

My invention relates to improvements in that class of centrifugalmachines in which rotation is permitted to take place about an, axis notcoincident with the axis of the machine, and it is the. object of myimprove-' ments to facilitate such rotation and to keep its axisstationary and vertical, as nearly as may be. i i i Referring to theaccompanying drawings,-

' forming part of this specification, Figure 1 isa verti -a'l section ofmy invention and Fig. 2 is a plan of some Fig. 1. v

' A shaft 1, adapted to carry the basket of a centrifugal machine at itslower end, is fixed to a pulley 2 driven by a belt 3. A drum 4 isintegral with the pulley and is used for stopping the machine by meansof i any suitable. brake. The shaft is supported by a head consisting ofa rotor in the form of a sleeve 5 anda grooved spool (3, a stator in theform of gronvcd rings 7 connected by a casing 8. andilballs Q-separatingthe two while maintaining their relative positions and permitting therotation of one Within the'other. T-he headis swingable with the shaftand rests upon a support which is yieldable to the swinging and whichconsists of a spherical zone 10 fitting asocket 11 in a hanger 12. Atube 13 retains oil used for lubrication and an opening in the top ofthe zone 10 permits circulation of the .other suitable. material,filling part of the space between the head and the hanger. and

secured to blocks 15 confined in the'hanger. When swinging occurstheheadrocks on and away from the abutment, leaving it at the top and thebottom alternately, and sliding toward and from it on the yieldable,support. The belt meanwhile tends to pull the head lmck-toward thabutment, whenever it rocks on and away from it, and thus urges themachine to verticality.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is:
